| Zusammenfassung: | A magnet knife assembly for a toner developing device including a ferromagnetic strip held between like poles (N) of two permanent magnets such that a knife edge portion of the strip projects outwardly beyond the two magnets and is subject to a magnet force that tends to urge the strip in a direction in which the knife edge projects further out of the magnets, wherein the length of the strip is selected such that a portion of the strip opposite to the knife edge is subject to a magnetic force that at least counterbalances said magnetic force on the knife edge portion. |
